LAAP's features:
Play ATC livestreams or prerecorded MP3s in your FSX using your plane's radio on COM1 or COM2 (read the manual on how to set to COM2).
Link on the left side is the link for the actual software.
Link on the right side is a livestream package for LAAP that I've put together myself. Please read the included install-instructions first! I've also included a frequency list within the zipfile...enjoy!!! :)
